The climate of the northeastern United States has undergone significant changes over the past 200 million years, transitioning from a warm, humid environment during the Mesozoic era, when dinosaurs roamed, to a cooler, temperate climate in the Cenozoic era. This shift has been influenced by tectonic activity, changes in sea levels, and glacial periods, particularly during the Pleistocene epoch, which shaped the region's landscape and ecosystems. Today, the northeastern US experiences four distinct seasons, with increasing concerns over climate change impacting weather patterns and temperatures. Overall, these long-term changes reflect the dynamic nature of Earth's climate system.
200 million years ago, Scotland was part of the supercontinent known as Pangaea. It was located near the equator, experiencing a warm and humid climate with lush vegetation. Scotland did not have its current shape and geography at that time.
